Cybersecurity Consulting Firm – Cyber Castellum
Uncover real-world vulnerabilities before attackers do. Our expert-led penetration testing services reveals your infrastructure most critical risks before they’re exploited by the bad guys.
Real Testing. Real Results.
Penetration testing is a manual effort supplemented by various tools to assess your IT infrastructure from a hacker perspective. Know your organization’s exposure, what information is publicly accessible, and the risk associated with it.
Our penetration tests emulate real attacker techniques to evaluate your environment’s true exposure. We assess your systems manually and strategically—revealing weak points, proving exploitability, and helping you prioritize remediation.
Our penetration tests go beyond checklists. We apply attacker mindset, certified expertise, and years of red team experience to expose what scanners can’t.
We simulate attacks from the outside world to evaluate perimeter defenses and public-facing systems.
Our experts mimic insider threats or post-breach actors to uncover internal risk exposures.
Identify logic flaws, insecure code, and bypassable features in web and mobile applications.
Test cloud environments and APIs for misconfigurations, insecure integrations, and exposed assets.
Evaluate wireless networks and user awareness through tailored phishing and physical attack simulations.
Receive clear, actionable reports, including business risk context and expert remediation guidance.
